RELATED APPLICATIONS

This application claims priority to Japanese Patent Application No.2020-165898, filed on Sep. 30, 2020, the entire content of which isincorporated herein by reference.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a biological monitoring device.

2. Description of the Related Art

Currently, a technique has progressively been developed so that amedical condition of a patient is detected by a sensor attached to amedical device or medical instrument used in a body of the patient andmedical treatment is performed on the patient, based on a detectedresult.

For example, Japanese Patent No. 4264472 discloses anintraoral-installing type biological monitor/treatment device includinga biological sensor, a signal processing unit, a communication unit, andan operating equipment unit.

The biological sensor is incorporated in a denture base or a mouthpiece.The biological sensor is a sensor that detects a pulse, a blood oxygenlevel, an enzyme or a metabolite in saliva, or an acceleration sensorthat detects a body posture or a motion. The signal processing unitevaluates data obtained from the biological sensor, detects an abnormalvalue, and stores the data. The communication unit wirelessly transmitsthe data in the signal processing unit to a network such as a homenetwork or the Internet via a network connector, and receives a commandsignal from a management center. The operating equipment unit is a drugpump operated based on the command signal transmitted from themanagement center via the network, a calling vibrator, or an intraoraltelephone device.

However, the above-described intraoral-installing type biologicalmonitor/treatment device receives the command signal from the managementcenter, and wirelessly transmits the data from the biological sensor tothe network to operate the operating equipment unit. However, theintraoral-installing type biological monitor/treatment device does nottransmit the data from the biological sensor to a patient. In addition,the data from the biological sensor does not always indicate contentswhich can be easily understood by the patient.

Therefore, the above-described intraoral-installing type biologicalmonitor/treatment device cannot notify the patient of informationrelated to treatment of the patient himself or herself. Therefore, evenwhen the intraoral-installing type biological monitor/treatment deviceis used, it may not be possible to increase a motivation of the patientfor the treatment in some cases.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment

An example of a biological monitoring device, a terminal, and a dataacquisition device according to an embodiment will be described withreference to FIGS. 1 to 5.

FIG. 1 is a view showing an example of an appearance of the biologicalmonitoring device according to the embodiment. FIG. 2 is a view showingan example of a cross section of a sensor device and a fixing unit whichare included in the biological monitoring device according to theembodiment. FIG. 3 is a view showing an example of the sensor device,the terminal, and the data acquisition device according to theembodiment.

As shown in FIGS. 1 and 2, a biological monitoring device 1 includes asensor device 10 and a fixing unit 11. As shown in FIG. 3, the sensordevice 10 includes a sensor 12, a processor 13, a storage unit 14, acommunication unit 15, and a battery 16.

The fixing unit 11 is a member that fixes the sensor device 10 in a bodyof a patient. For example, an interior of the body of the patientreferred to herein is an interior of an oral cavity, a nasal cavity, oran ear canal of the patient. However, the interior of the body of thepatient referred to herein may include sites other than the oral cavity,the nasal cavity, and the ear canal of the patient.

For example, as shown in FIGS. 1 and 2, the fixing unit 11 is partiallyconnected to an orthodontic appliance 700, and is a resin-made memberfor fixing the sensor device 10 to an outer side of a mandibular body ofa mandible bone of the patient. As shown in FIG. 2, it is preferablethat the fixing unit 11 seals the sensor device 10 to avoid water suchas saliva of the patient from adhering to the sensor device 10.

The sensor 12 is included in the sensor device 10, performs a detectionprocess of detecting a medical condition of the patient, and performs aprocess of generating first detection data indicating a result of thedetection process. For example, the first detection data is dataindicating a physical quantity detected by the detection process, andmay indicate whether or not the detection process is normally performed.The sensor 12 may be controlled by an integrated circuit (IC), and mayintermittently be operated every 10 seconds, for example.

For example, the sensor 12 is a pulse oximeter. The pulse oximeterincludes a light emitting element such as a light emitting diode (LED)and a photo detection element. The pulse oximeter applies light outputfrom the light emitting element to an inner side of a cheek of thepatient, and causes the photo detection element to detect the lightreflected on the cheek of the patient. The pulse oximeter measures ablood oxygen level, based on the light detected by the photo detectionelement, and generates first detection data indicating the blood oxygenlevel of the patient.

However, for example, the sensor 12 may be a chemical sensor, anacceleration sensor, a gyro sensor, a pressure sensor, a strain sensor,a pulse wave sensor, a heart rate sensor, or a blood flow sensor.

The chemical sensor is a sensor that generates the first detection dataindicating a type or the number of bacteria existing in the body of thepatient by detecting the presence or absence of a specific chemicalsubstance existing in the body of the patient, or by measuring aconcentration of the specific chemical substance existing in the body ofthe patient.

The acceleration sensor is a sensor that performs a detection process ofmeasuring acceleration of a part of the body of the patient, andgenerates the first detection data indicating the number of walkingsteps, the amount of activity, and a movement of the part of the body,for example. The gyro sensor is a sensor that performs a detectionprocess of measuring an angular velocity of a part of the body of thepatient, and measures the number of walking steps, the amount ofactivity, and a movement of the part of the body, for example. Forexample, the part of the body of the patient referred to herein is a jawof the patient.

When the biological monitoring device 1 is attached to the jaw of thepatient, and the sensor 12 includes at least one of the accelerationsensor and the gyro sensor, for example, the sensor 12 generates thefirst detection data indicating the number of chewing times of thepatient, the number of swallowing times of the patient, and the numberof teeth grinding times.

The pressure sensor is a sensor that performs a detection process ofmeasuring a pressure applied to a part of the body of the patient, andgenerates the first detection data indicating a movement of the part ofthe body of the patient. The strain sensor is a sensor that performs adetection process of measuring a strain applied to a part of the body ofthe patient, and generates the first detection data indicating amovement of the part of the body of the patient. For example, the partof the body of the patient referred to herein is a jaw of the patient.

When the biological monitoring device 1 is attached to the jaw of thepatient, and the sensor 12 includes at least one of the pressure sensorand the strain sensor, for example, the sensor 12 can measure amagnitude of a force applied to teeth, artificial teeth, and anorthodontic appliance by the number of chewing times and chewing. Inthis case, for example, the sensor 12 can measure a magnitude of a forceapplied to teeth, artificial teeth, and an orthodontic appliance by thenumber of swallowing times, the number of teeth grinding times, andteeth grinding, or a time during which the orthodontic appliance ismounted.

The pulse wave sensor is a sensor that measures a pulse wave by usingthe light, and generates the first detection data indicating the pulsewave of the patient. The heart rate sensor is a sensor that measures aheart rate of the patient by using the light, and generates the firstdetection data indicating the heart rate of the patient. The blood flowsensor is a sensor that measures a blood flow of the patient by using alaser, and generates the first detection data indicating the blood flowof the patient.

When a sensor using the light such as the laser is included in thesensor 12, at least a portion of the fixing unit 11 needs to be made ofa material that transmits the light. For example, when a sensor usingthe light having a wavelength belonging to a near infrared region or avisible light region is included in the sensor 12, at least a portion ofthe fixing unit 11 needs to be made of a material that transmits thelight having a wavelength of 400 nm to 1,000 nm.

For example, the processor 13 is a central processing unit (CPU). Theprocessor 13 reads and executes a program stored in the storage unit 14,and realizes a function of controlling the sensor 12, a function ofcontrolling the communication unit 15, and other functions. Theprocessor 13 reads and executes a program stored in the storage unit 14,and realizes a generation unit 131, a determination unit 132, and acontrol unit 133 which will be described later.

For example, the storage unit 14 includes a read only memory (ROM) and arandom access memory (RAM). For example, the ROM included in the storageunit 14 stores the program read and executed by the processor 13. On theother hand, in the RAM included in the storage unit 14, the program readand executed by the processor 13 is developed. Furthermore, the storageunit 14 stores the first detection data generated by the sensor 12.

The communication unit 15 communicates with the terminal 2, the dataacquisition device 3, and other devices which are shown in FIG. 3. Forexample, the communication unit 15 communicates with the terminal 2, thedata acquisition device 3, and other devices by using wirelesscommunication such as Bluetooth (registered trademark) Low Energy (BLE).In this case, the communication unit 15 has a circuit corresponding to aBLE standard.

The terminal 2 is a terminal such as a smartphone or a tablet associatedwith the patient on which the biological monitoring device 1 is mounted.For example, the terminal includes a terminal associated with thepatient himself or herself on which the biological monitoring device 1is mounted, a guardian of the patient, or an attending physician of thepatient. The terminal 2 may perform a scan response to the biologicalmonitoring device 1 when necessary, and may request the biologicalmonitoring device 1 to additionally transmit second detection data.

The data acquisition device 3 acquires the first detection datagenerated by the biological monitoring device 1, and transmits the firstdetection data to a computer used by the attending physician, a dentalhygienist, or a nurse of the patient. For example, the first detectiondata is used in the computer for examining an advantageous effect oftreatment performed on the patient, examining a future treatment policy,and analyzing a medical condition of the patient.

The battery 16 supplies power to each unit of the sensor device 10, forexample, the sensor 12, the processor 13, the storage unit 14, and thecommunication unit 15.

FIG. 4 is a view showing an example of a functional configuration of thebiological monitoring device according to the embodiment.

As shown in FIG. 4, the biological monitoring device 1 includes thegeneration unit 131, the determination unit 132, and the control unit133. The generation unit 131, the determination unit 132, and thecontrol unit 133 are realized in such a manner that the processor 13reads and executes a program stored in the storage unit 14.

The generation unit 131 indicates contents related to a detectionprocess performed by the sensor 12, and performs a process of generatingthe second detection data having a smaller data volume than the firstdetection data, based on the first detection data. The generation unit131 may continuously perform the process of generating the seconddetection data, as long as the sensor 12 continuously perform thedetection process.

For example, the second detection data indicates a portion of thecontents indicated by the first detection data, a value calculated basedon the first detection data, and the amount of power that can besupplied to the sensor 12 by the battery 16. Unlike the first detectiondata, the second detection data is not data used by the attendingphysician, the dental hygienist, or the nurse of the patient for thetreatment of the patient or a medical research, and is a history ofusing the orthodontic appliance 700 or data used to easily notify thepatient of a past health condition of the patient. Therefore, it ispreferable that the second detection data indicates the contents thatare easy for the patient to understand rather than medically accuratecontents.

The second detection data is transmitted to the terminal 2 by thecommunication unit 15. In this case, the communication unit 15 maytransmit the second data to the terminal 2 without receiving a requestfor transmitting the second detection data to the terminal 2. Forexample, the communication unit 15 may transmit the second detectiondata to the terminal 2 by using an advertising packet, a beacon, or abroadcast.

FIG. 5 is a view showing an example of an image displayed on a displaymounted on the terminal, based on the second detection data generated bythe sensor device 10 according to the embodiment. An image P shown inFIG. 5 includes a display region A1, a display region A2, and a displayregion A3.

A region having horizontal line hatching displayed in the display regionA1 indicates a range in which a health index is relatively low. A regionhaving dot hatching displayed in the display region A1 indicates a rangein which the health index is approximately medium. A region havingvertical line hatching displayed in the display region A1 indicates arange in which the health index is relatively high.

A region having oblique hatching displayed in the display region A1 is acursor indicating a current health index of the patient. For example, asshown in FIG. 5, when the cursor indicates a health index in the regionhaving the vertical line hatching, it is displayed in the display regionA1 that the health index is “A”. Alternatively, when the cursorindicates a health index in the region having the dot hatching, it isdisplayed in the display region A1 that the health index is “B”.Alternatively, when the cursor indicates a health index in the regionhaving the horizontal line hatching, it is displayed in the displayregion A1 that the health index is “C”.

The display region A2 displays a graph of a blood oxygen level measuredby the sensor 12. In the graph, a horizontal axis represents a time, anda vertical axis represents the blood oxygen level. The graph shown inFIG. 5 shows an example of a measurement result when the blood oxygenlevel increases toward a normal blood oxygen level after the bloodoxygen level gradually and continuously decreases.

The display region A3 indicates that a current body temperature of thepatient is “36.6° C.”, a pulse is “112 bpm”, and the blood oxygen levelis “99%”, and indicates that a fitting force of the patient is weak.

The determination unit 132 determines whether or not the sensor device10 exists in the body of the patient, based on at least one of the firstdetection data and the second detection data. For example, thedetermination unit 132 determines that the sensor device 10 exists inthe body of the patient, when at least one of the blood oxygen levelindicated by the first detection data and the blood oxygen levelindicated by the second detection data is relatively close to the bloodoxygen level of a healthy person. On the other hand, the determinationunit 132 determines the sensor device 10 does not exist in the body ofthe patient, when at least one of the blood oxygen level indicated bythe first detection data and the blood oxygen level indicated by thesecond detection data is not a significant blood oxygen level.

When it is determined that the sensor device 10 exists in the body ofthe patient, the control unit 133 controls the communication unit 15 totransmit the second detection data to the terminal 2 in a first cycle.The first cycle is a cycle that can be set to any desired length, and isfive minutes, for example. On the other hand, when it is determined thatthe sensor device 10 does not exist in the body of the patient, thecontrol unit 133 controls the communication unit 15 to transmit thesecond detection data to the terminal 2 in a second cycle shorter thanthe first cycle. The second cycle is a cycle that can be set to anydesired length, and is 5 seconds, for example.

A wireless signal transmitted to the terminal 2 by the communicationunit 15 is greatly attenuated by receiving influence of water existingin the body or a tissue of the patient. Therefore, the communicationunit 15 needs to increase intensity of the wireless signal to transmitthe second detection data to an outside of the body when the sensordevice 10 exists in the body of the patient than when the sensor device10 exists outside the body of the patient. Therefore, the communicationunit 15 consumes more power when the sensor device 10 exists in the bodyof the patient.

The determination unit 132 may calculate a time during which the sensordevice 10 does not exist in the body of the patient, based on at leastone of the first detection data and the second detection data, and mayfurther determine whether or not the time exceeds a predeterminedthreshold. When it is determined that the time exceeds the predeterminedthreshold, the control unit 133 may lengthen the second cycle. In thiscase, the control unit 133 may lengthen the second cycle within a rangenot exceeding a length of the first cycle, or may lengthen the secondcycle regardless of the length of the first cycle.

The determination unit 132 may calculate a time during which the sensordevice 10 does not exist in the body of the patient, based on at leastone of the first detection data and the second detection data, and mayfurther determine whether or not the time exceeds a predeterminedthreshold. When it is determined that the time exceeds the predeterminedthreshold, the generation unit 131 generates recommendation data forcausing the terminal 2 to perform a process of outputting informationfor recommending the patient to be in a state where the sensor device 10exists in the body of the patient. The recommendation data istransmitted to the terminal 2 by the communication unit 15, and is usedby the terminal 2 to output the information by using a display or aspeaker mounted on the terminal 2.

Next, an example of a process of determining a cycle in which thebiological monitoring device according to the embodiment transmits thesecond detection data to the terminal will be described with referenceto FIG. 6.

FIG. 6 is a flowchart showing an example of the process of determiningthe cycle in which the biological monitoring device according to theembodiment transmits the second detection data to the terminal. Theprocess shown in FIG. 6 is a process performed on a premise that thesensor 12 and the generation unit 131 are continuously operated.

In Step S1, the determination unit 132 determines whether or not thesensor device 10 exists in the body of the patient. When thedetermination unit 132 determines that the sensor device 10 exists inthe body of the patient (Step S1: YES), the process proceeds to Step S2.On the other hand, when the determination unit 132 determines that thesensor device 10 does not exist in the body of the patient (Step S1:NO), the process proceeds to Step S3.

In Step S2, the control unit 133 controls the communication unit 15 totransmit the second detection data to the terminal 2 in the first cycle.

In Step S3, the determination unit 132 calculates a time during whichthe sensor device 10 does not exist in the body of the patient, based onat least one of the first detection data and the second detection data.

In Step S4, the determination unit 132 determines whether or not thetime during which the sensor device 10 does not exist in the body of thepatient exceeds a predetermined threshold. When the determination unit132 determines that the time during which the sensor device 10 does notexist in the body of the patient exceeds the predetermined threshold(Step S3: YES), the process proceeds to Step S5. On the other hand, whenthe determination unit 132 determines that the time during which thesensor device 10 does not exist in the body of the patient is equal toor smaller than the predetermined threshold (Step S3: NO), the processproceeds to Step S7.

In Step S5, the control unit 133 lengthens the second cycle.

In Step S6, the control unit 133 controls the communication unit 15 totransmit the second detection data to the terminal 2 in the secondcycle.

In Step S7, the generation unit 131 generates recommendation data forcausing the terminal 2 to perform a process of outputting informationrecommending the patient to be in a state where the sensor device 10exists in the body of the patient.

In Step S8, the communication unit 15 transmits the recommendation datato the terminal 2.

Hitherto, the biological monitoring device 1 according to the embodimenthas been described.

The biological monitoring device 1 includes the sensor 12, thegeneration unit 131, and the communication unit 15. The sensor 12 isincluded in the sensor device 10, performs a detection process ofdetecting a medical condition of the patient, and performs a process ofgenerating first detection data indicating a result of the detectionprocess. The generation unit 131 is realized by the sensor device 10,indicates the contents related to the detection process, and performsthe process of generating the second detection data having a smallerdata volume than the first detection data, based on the first detectiondata. The communication unit 15 is realized by the sensor device 10, andperforms the process of transmitting the second detection data to theterminal 2 associated with the patient.

In this manner, the biological monitoring device 1 can transmit thesecond detection data to the terminal 2 associated with the patient, caneasily notify the patient of the contents of the detection process, andcan increase a motivation of the patient for a detection process ofdetecting a medical condition of the patient.

The biological monitoring device 1 can notify the patient of informationrelated to a health condition of the patient himself or herself, whenthe second detection data indicates the blood oxygen level of thepatient, the number of walking steps, the amount of activity, and a typeor the number of bacteria existing in the body. Furthermore, thebiological monitoring device 1 can notify the patient of informationrelated to a tooth condition of the patient himself or herself, when thesecond detection data indicates the number of chewing times of thepatient, a magnitude of a force applied to teeth, artificial teeth, andan orthodontic appliance by the number of chewing times of the patientand chewing, or a magnitude of a force applied to the teeth, theartificial teeth, and the orthodontic appliance by the number of teethgrinding times and teeth grinding.

The biological monitoring device 1 transmits the second detection datato the terminal 2 without receiving a request for transmitting thesecond detection data to the terminal 2.

In this manner, the biological monitoring device 1 does not communicatewith the terminal 2 before transmitting the second detection data to theterminal 2. Accordingly, the biological monitoring device 1 can save thepower supplied from the battery 16, and can continuously extend theoperable time.

When it is determined that the sensor device 10 exists in the body ofthe patient, the biological monitoring device 1 controls thecommunication unit 15 to transmit the second detection data to theterminal 2 in the first cycle. On the other hand, when it is determinedthat the sensor device 10 does not exist in the body of the patient, thebiological monitoring device 1 controls the communication unit 15 totransmit the second detection data to the terminal 2 in the second cycleshorter than the first cycle.

That is, when the biological monitoring device 1 needs to consume alarge amount of the power to transmit the second detection data to theterminal 2 since the sensor device 10 exists in the body of the patient,the biological monitoring device 1 adopts the first cycle longer thanthe second cycle, as a cycle for transmitting the second detection data.

In this manner, when the biological monitoring device 1 needs to consumea large amount of the power to transmit the second detection data to theterminal 2, the biological monitoring device 1 adopts the first cyclelonger than the second cycle. Accordingly, the biological monitoringdevice 1 can save the power supplied from the battery 16, and cancontinuously extend the operable time.

The biological monitoring device 1 calculates a time during which thesensor device 10 does not exist in the body of the patient, based on atleast one of the first detection data and the second detection data, anddetermines whether or not the time exceeds the predetermined threshold.When it is determined that the time exceeds the predetermined threshold,the biological monitoring device 1 lengthens the second cycle.

In this manner, the biological monitoring device 1 does not need totransmit the second detection data to the terminal 2 since the sensordevice 10 does not exist in the body of the patient, the biologicalmonitoring device 1 can lengthen the second cycle, can save the powersupplied from the battery 16, and can continuously extend the operabletime.

The biological monitoring device 1 calculates a time during which thesensor device 10 does not exist in the body of the patient, based on atleast one of the first detection data and the second detection data, anddetermines whether or not the time exceeds the predetermined threshold.Next, when it is determined that the time exceeds the predeterminedthreshold, the biological monitoring device 1 generates therecommendation data for causing the terminal to perform the process ofoutputting the information for recommending the patient to be in a statewhere the sensor device 10 exists in the body of the patient. Thebiological monitoring device 1 transmits the recommendation data to theterminal 2.

In this manner, when the sensor device 10 does not exist in the body ofthe patient, the biological monitoring device 1 can urge the patient tomount the biological monitoring device 1, and can more reliably achievean advantageous effect of treatment using the biological monitoringdevice 1. In this manner, when the sensor device 10 does not exist inthe body of the patient, the biological monitoring device 1 urges thepatient to mount the biological monitoring device 1, and can morereliably recognize the health condition obtained by using the biologicalmonitoring device 1.

The biological monitoring device 1 includes the storage unit 14 thatstores the first detection data. In this manner, the biologicalmonitoring device 1 may only store the first detection data in thestorage unit 14 as long as the biological monitoring device 1 doers notreceive a request for transmitting the first detection data from thedata acquisition device 3. Therefore, the biological monitoring device 1does not need to consume the power stored in the battery 16 to transmitthe first detection data, and can continuously extend the operable time.

At least some of the functions of the biological monitoring device 1 maybe realized by hardware including circuit units (circuitry) such asLarge Scale Integration (LSI), Application Specific Integrated Circuit(ASIC), and Field-Programmable Gate Array (FPGA).

The sensor device 10 described above does not need to be fixed to theorthodontic appliance 700 by the fixing unit 11. For example, the sensordevice 10 may be fixed to a sprint used by the patient. Even in thiscase, the biological monitoring device can fix the sensor device 10 inthe body of the patient without invading the body of the patient.

In the above-described embodiment, a case where the biologicalmonitoring device 1 is one device has been described as an example.However, the present invention is not limited thereto. For example, apart of the biological monitoring device 1 may be realized by a firstdevice, and another part of the biological monitoring device 1 may berealized by a second device different from the first device. However, itis preferable that all of the devices are sealed by the fixing unit 11.

In the above-described embodiment, a case where the sensor device 10 issealed by the fixing unit 11 has been described as an example. However,the present invention is not limited thereto. For example, the fixingunit 11 may only cover a portion of the sensor device 10.

In the above-described embodiment, a case where the sensor device 10includes the CPU, the ROM, and the RAM has been described as an example.However, the present invention is not limited thereto. For example, thesensor device 10 may include a microprocessor having these threefunctions instead of the CPU, the ROM, and the RAM.

In the above-described embodiment, a case where the sensor device 10 isconnected to the orthodontic appliance 700 by the fixing unit 11 hasbeen described as an example. However, the present invention is notlimited thereto.

FIG. 7 is a view showing an example of an appearance of a biologicalmonitoring device according to another embodiment.

As shown in FIG. 7, a biological monitoring device 1 a includes a sensordevice 10 a in a portion which covers an anterior tooth of the patientin an orthodontic appliance 800 mounted on a lower jaw of the patient.The sensor device 10 a includes a pressure sensor that measures afitting force of the patient.

FIG. 8 is a view showing an example of a fitting force measured by thesensor device included in the biological monitoring device according toanother embodiment.

In FIG. 8, a horizontal axis represents a time, and a vertical axisrepresents the fitting force. During a period T1 and a period T3 whichare shown in FIG. 8, the pressure sensor does not measure a significantmagnitude of the fitting force. On the other hand, during a period T2shown in FIG. 8, the pressure sensor measures the fitting force when thepatient fits an upper jaw and a lower jaw. In a first half of the periodT2, the fitting force increases as the patient starts to fit the upperjaw and the lower jaw. In a second half of the period T2, the fittingforce shows a substantially constant magnitude since the patientfinishes fitting the upper jaw and the lower jaw.

In this case, for example, the determination unit 132 determines thatthe sensor device 10 exists in the body of the patient, when the numberof times that at least one of the fitting force indicated by the firstdetection data and the fitting force indicated by the second detectiondata exceeds a predetermined fitting force exceeds a predeterminednumber of times during a predetermined period. On the other hand, thedetermination unit 132 determines that the sensor device 10 does notexist in the body of the patient, when a period during which at leastone of the fitting force indicated by the first detection data and thefitting force indicated by the second detection data is smaller than thepredetermined fitting force continuously exceeds the predeterminedperiod.

Hitherto, the embodiments of the present invention have been describedin detail with reference to the drawings. However, specificconfigurations of the embodiments of the present invention are notlimited to the above-described embodiments, and at least one of variouscombinations, modifications, substitutions, and design changes may beadded to the above-described embodiments within the scope not departingfrom the concept of the present invention. Accordingly, the invention isnot to be considered as being limited by the foregoing description andis only limited by the scope of the appended claims.
